Some Plains people were not hunters and gatherers. They were farmers. They lived in villages. They lived in round earth lodges. These were huge things. Some were 40 feet in diameter and about 15 feet high. They were earthy, but warm in the winter and cool in the summer. These were fixed structures.
The Plateau people were hunters and gatherers. They had three homes. They lived in a pit home in the winter, a summer home, and a temporary home.
